The following maps identify demographic characteristics within 1/4-mile euclidean buffers of roadway segments in the study corridor. They review the median age, percent of households with 0 vehicles, and percent of persons with a disability within 1/4-mile of each roadway analysis segment.
Demographic data are obtained from the 2019 American Community Survey for disabilities (tract), age (block group), and 0 vehicle households (tract). Estimates are disaggregated weighted by building footprints with relative land use weights. Roadway segments are split into analysis components no longer than 500-feet, and a 1/4-mile buffer is generated around each segment and the population characteristics are summarized, weighting by both area and population.
Each land use is assigned a relative weight for both population and employment. These weights are applied in conjunction with building footprint areas in order to disaggregate all population and employment within each TAZ to the building footprint level. The tables below document weights applied. In this table, a value of 0 represents no allocation is made. 3 represents “high”, or 3 times as many. Land use weights are applied in combination with building footprint area. Note that demographic variables are only disaggregated to areas with existing buildings.

The following maps shows median age within 1/4-mile buffers of each roadway segment and where median age exceeds the state average of 42.
The following maps show percent of population with one or more disabilities within 1/4-mile buffers of each roadway segment and where this percent exceeds the state average of 15.5 percent.
The following maps show percent of households within 1/4-mile buffers of each roadway segment with 0 households. A second map shows where this average exceeds the state average.
